Preview Time not accurate ( already did "Read from controller" )

So in console type
$1=250
press enter
(This makes your steppers be FULLY energized all the time, is this something you want?

$23=3
press enter
$39=0
press enter
$100=80
press enter
$101=80
press enter
$110=10000
press enter
$111=10000
press enter
$120=2000
press enter
$121=1800
press enter
(these are a guess estimate, you might need to lower them a tad)

Okay, did that but now it has a bigger problem. It says that it’s in X-2010 Y-1481.
I tried to go upwards by only 1mm it bugged and went down like a lot. I shut down immediately.

Help :frowning:

power it off and power it back on
It has no homing enabled so the moment you power it on it should have a Xo Yo

Type ? in console and see what it says in MPos

Okay, it works :slight_smile:

Now I need to test it ?

Dot Test with Angle.lbrn (46.3 KB)
Run this for me please

Send you the result ?

yes please upclose picture if you can

this good ?

mmm you have a little issue with your bottom end, is marking on the traverse movements

Also… your Y belts seem a bit loose
Notice how the Y right side is a bit wonky and your Circle is not a circle but more an oval

But 1 issue at a time
a) what GRBl controller have you selected GRBL or GRBL M3
b) edit _> device settings. Svalue Max is set to?
c) you need to review your belts
d) if you can. on iddle what reading you get measureing GRD + PWM

a) Where do I see that
b) 1000
c) I will
d) I have to see, can’t right at this moment.

@gilaraujo can we just talk via mail or something ?

Click Devices button in laser panel
Double click your Profile
See which GRBL is selected
3 options
GRBL
GRBL_LPC
GRBL-M3

You want top one

they upgraded me to a trusted user, I was a newbie before :smiley:

Shall we continue ?

sure thing! what have you gotten set?

a) It’s a GRBL
b) It’s 1000
c) It’s my first time doing it so I have to search how to actually do tha
d) What I need to get from it ?

Belts is easy
Take a couple pictures of your belts

As per PWM test with multimeter
If able, take a multimeter, measure the GRD + PWM combo while machine is ON but not engraving
You should get a 0V

Then try 1% (fire button)
You should get 0.3v

If you dont get 0V on iddle, something is leaking voltage into your PWM so make sure is correct and no wiring needs review

Should I take them out / dissasemble the machine, or just like take a picture ?

I get 0 V on idle, 0.4 ~ V on 1% power.

this is odd, which means your machine should NOT engrave while moving across and yet it is
Something obvious might show on belts

What can I do about that

The belts are really dirty, maybe that’s the problem.
